A paved plaza would be transformed into a
functional oasis where storm water is captured
by permeable pavers and gray and black water
is filtered through a microalgae pond.

Process Zero.

Research led Quinn to an emerging
technology. Scientists have tested
large-scale cultivation of microalgae
in horizontal and vertical glass tubes,
rather than in open-air ponds. Quinn
transferred the mechanics of tube
technology to the side of a building,
adding a full-scale closed system of
